gas and boggles. intake back fire?

[AsanBBoy]

So it idles fine, but give it some gas it boggles like hell and could die. I guess it seems to have a intake back fire form the sounds of it. There is a lag between throttle and sucking inn air. Reving it any higher than 3 is not possible most of the time. It is throwing no codes and i do not know what to do next. Any help? I have a video don't know if it will help much (I took it side ways...).

edit, perhaps the timing chain is off? I dunno how though. When I was running the car with a turbo set up, it was idling fine and reving fine. Now this?

- check the MAF- possible major vacuum leak

[AsanBBoy]

Yes I have my mafs on. When i start it without it, idle is bad it jumps up and down to about 1000rpms and dips to about it dies but it doesn't. Bad mafs? I do have another one but i think i tried swaping it out already.

Check your vacuum lines, sounds like you might have a leak

sounds like one of the injectors is not pulsing, check your oil to see if it smells like gas.
